Industry:Weather
Stream that is separated from the underlying groundwater by a zone of unsaturated material. Compare insulated stream.
Industry:Weather
Stream of ionized gas, mainly hydrogen, continuously flowing outward from the sun, at very high velocity (≈ 400 km s<sup>−1</sup> on the average) and with variable intensity. While passing near the earth the solar wind interacts with the magnetic field to produce various effects in the upper atmosphere (e.g., aurora).
